Hi All,
I am currently working on a project that requires a 0-10V DC supply to be converted into a linear fequency range - square wave. for instance 1V to be a low frequency square wave with the frequency increasing exponetially as the input voltage is increased.
So far i have been playing arround with a simple 555 timer which appears to work however it works the wrong way. (low voltage is high frequency and high voltage is low frequency).
Is there any way this can be reversed?
Does anyone have any other ideas of how this can be achieved with minimum cost issues??
( I am hoping to redesign an excisting circuit which creates the Squarewave output using a MUX and conparator therefore would hope to keep components and costing to a minimum )
Thanks all,
Rob
